HARRY E. EURICH, OF OTSEGO, MICHIGAN.

BEATEB Application me@ August l8,*1924r.. Serial No'. 730,853.

- To all 'whom t may concern Be it kng. n that I, HARRY E. EURICH, a citizen of the United States,l residing at Otsego, county of Allegan, State of M ichigan, have invented certain new and useful Improvements in Beater Engines, of which the following is a specification.

This invention relates to improvements in beater engines.

The main object of this invention is to provide an improved beater engine having a continuous discharge.

A further object is to provide an improved beater engine which is of. large capacity.

Objects pertaining to details and econo.- mies of construction and operation of'my improvements will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly, illustrated in the accompanying' drawing forming a part of this application, in which:

Fig. I is a plan view of a beater engine embodying the features of my invention, parts being shown mainly in conventional form for convenience in illustration.

Fig. II is a fragmentary view partially in vertical section on a line corresponding to line 2-2 of Fig. I looking in the direction of the arrows.

In the drawing similar reference numerals refer to similar parts in both views.

Referring to the drawing, the embodiment of my invention illustrated comprises .the elongated tank 1 having a central midfeather 2 at one side of which the beater roll 3 and the coacting backfall 4 are disposed. These parts are shown conventionally as the structure thereof is well known in the art.

At the ends provided with discharge openings 5 which deliver to the stock chest orto a spout not here illustrated. The foraminated drums 6 are disposed vertically to embrace these discharge openings, the drums being supported and driven by the vertically disposed shafts 7, the lower ends of whic are carried by the stirrup-like hangers 8 and the upper ends of the shafts being supported by the arms 9.

On the upper end of the shaft is a beveled gear 10 driven from the gear- 11 on the jack shaft 12 connected to a suitable source of power as by the belt 13. The lower end of the drum is embraced by an annular guardv 14 which prev ents the stock flowing directly under the drum. Within the drum is a cylindrical Weir 15 open at the top and bottom, the Weir surrounding the. discharge openingr 5.y The Weir is provided with a collar 16 at its upper end secured to .the shaft by means of the set screw 17 so that the Weir rotates with theshaft. i The Weir is surrounded by the guard 18.

This'weir is of proper height to determine the flow of strained stock and alsorelieves the screen of excessive pressure, that is, if there were no head Within the screen a large 'amount of'water would be drawn ol' from .the -beater and the screen would be subjected Athe rear of the doctor blades to discharge against the screens, either steam or Water, as

may be desired, so that clogging the screens is effectively prevented.

My improved beater engine is of large capacity, the stock being continuously drawn oli or discharged, and this without clogging. I am aware that beater engines having continuous discharges have been provided but my experience is that these are not eiiicient in that they rapidly become clogged or the Vdischarges are of restricted capacity. EX-

perience` has demonstrated that in my improved beater engine this difculty is not present. of the midfeather the tank is Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

' 1. The combination in a beater engine comprising a tank provided with a midfeather, a beater roll and a coacting backfall, of a foraminated drum open at the bottom disposed vertically at one end of said midfeather, there being a discharge opening in the bottom of the tank within said drum, a supporting and driving shaft for said drum,

a cylindrical weir surrounding said discharge opening and adjustably mounted ,on said shaft. a doctor blade mounted on said midfcatlicr to coact with said drum, and a spray pipe disposed behind saidA doctor blade and directed against said drum.

2. The combination in'a beater' engine comprising a tank provided With a midfeather, a beater roll and a coacting back fall, of a foraminated drum open at the bottom disposed vertically at one end of Said niid't'cather` there being a discharge openingr in the bottom of the tank within said drum, a supporting and driving shat't for said drum, a c vliinlrical Weir surrounding said discharge vopening and adjustably mounted on said shaft, and a doctor blade mounted on said inidfcathcr to coact With said drum.

3. The combination in abeater engine comprising a tank provided with a midt'eather, a beater roll and a coacting backiall, of a toraniinated drum open al the bot-`y tom disposed vertically at one end of said midtcather, there being a discharge opening in the bottom of the tank Withnsaid drum, a supporting and driving shaft for said drum, and a cylindrical Wirsurrounding said discharge opening and adjustably mounted on said shaft. -1- i 4. The combination in a beater enginey comprising a tank provided With a midlfcatllei-,a beater roll and a coactmg backfall, ol' a foraininated druln open at the bottom disposed vertically at one end of said inid't'eather, there beine' ing in the bottom of the tank within said drum, a supporting and driving shaft for said drum, an annular guard mounted on the bottom of said tank to embrace the bottom of said drum, and a cylindrical Weir surrounding said discharge opening and adjnstably mounted on said shaft.

5. The combination in a beater engine including a tank having a discharge opening in the bottom thereof, of a cylindrical screen open at the bottom and disposed vertically in said tank to embrace said discharge opening thereof, means for rotating said screen, a Weir dis osed Withln said screen to surround sa-i discharge opening, a. doctor a discharge open vblade coacting with said screen, and a spray pipe disposed to discharge ainst said screen at the rear of said doctor lade.

6. The combination in a beater engine including a tank having a discharge opening in the bottom thereof, of a cylindrical screen open at the bottom' and disposed vertically in said tank to embrace said dischar e opening thereof, meansfor rotating sai screen, a weir disposed Within said screen to snrround said discharge opening, and a doctor blade coat-tine' with said Screen.

7. The combination in a beater engine including a tank having a discharge opening in the bottom thereof, of a cylindrical screen open at the bottom and disposed vertically in said tank to embrace said discharge opening thereof, means for rotating said screen, a weir disposed within said screen to surround said discharge opening, and a spray pipe disposed to discharge against said screen.

8. The combination in a beater engine including a tank having a discharge opening in the bottom thereof, of a cylindrical screen open at the bottom and disposed vertically in said tank to embrace said discharge opening thereof, means for rotatin said screen, and a Weir disposed within sai screen to surround said discharge opening.

9. The combination in a beater engine including a tank yhaving a discharge o ening of a cylindrical screen open at the ottom disposed vertically in said tank to embrace said discharge opening, means for driving said screen, and a Weir dis sed within said screen to enclose said disc arge opening, said Weir being vertically7 adjustable and constitutinga drain valve for the tank.

10. The combination in a beater engine including a tank having a discharge opening, of a cylindrical screen open at the bottom disposed vertically in said tank to em-l brace said discharge opening, and means for driving said screen.

In Witness whereof I. have hereunto set my hand.
